Description

[0001] This application is a divisional application of a cloth - clamping mop that is convenient for replacing the mop cloth. The original application date: December 29, 2023; the original application number: CN202323641645.7; the original invention creation name: A cloth - clamping mop that is convenient for replacing the mop cloth. Technical Field

[0002] The utility model relates to the field of cloth - clamping mops, in particular to a cloth - clamping mechanism of a cloth - clamping mop. Background Art

[0003] Mops are often used for floor cleaning. The mop cloth is installed on the mop head, and the mop handle is held to clean the floor. Most mops on the market use fixed mop cloths. It is rather troublesome to replace the mop cloth. The mop cloth is often used for a long time and will become a place for hiding dirt and grime after multiple uses. If directly discarded, it will cause unreasonable use of resources and waste. To solve this problem, people have designed cloth - clamping mops with replaceable mop cloths.

[0004] For example, the patent number CN219846427U discloses a cloth - clamping mop that is convenient for replacing the mop cloth. Its mop rod includes an outer rod connected to the mop bottom plate and an inner rod slidably connected inside the outer rod. A screw rod (twisted rod) is arranged inside the inner rod, and at least part of the inner wall of the inner rod cooperates with the screw rod. Among them, the screw rod is connected to the driving component through a connecting piece. When clamping, the inner rod is pressed down. Since the inner wall of the inner rod cooperates with the screw rod, the screw rod can be driven to rotate in the opposite direction, and then through the connecting piece, the driving gear is driven to rotate in the opposite direction, so as to drive the second clamping piece to approach the first clamping piece, making the two clamp the mop cloth. In the above structure, its driving structure using a twisted rod and a driving gear can achieve clamping of the mop cloth, but the driving process is relatively complex, there are many driving components, and having a twisted rod inside the mop rod will inevitably increase the weight of the mop rod, making it more laborious to mop the floor.

[0038] The following will describe the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

[0039] Refer to Figures 1 to 9 , the present utility model provides a cloth clamping mechanism for a cloth mop, including a mop head 1, a mop rod 2, a cloth clamping assembly 3, and a driving assembly 4.

[0040] Refer to Figure 3 and Figure 4 , the mop rod 2 is installed at the upper end of the mop head 1. The mop rod 2 includes an outer rod 21 hinged to the mop head 1 and an inner rod 22 slidably installed within the outer rod 21. The cloth clamping assembly 3 is installed at the bottom of the mop head 1 for clamping the mop cloth, and the mop cloth can be a thin non-woven fabric. The cloth clamping assembly 3 includes a main clamping member 31 fixed to the mop head 1 and movable clamping members 32 slidably installed on one or both sides of the main clamping member 31. The driving assembly 4 is disposed within the mop head 1 for driving the cloth clamping assembly 3 to clamp or loosen. The driving assembly 4 includes a sliding seat 41 slidably installed vertically on the mop head 1 and a pull rod 42 with one end hinged to the mop head 1. The other end of the sliding seat 41 is drivingly connected to the inner rod 22, and the other end of the pull rod 42 can be hinged to the movable clamping member 32 directly or indirectly. A pressure post 411 is provided on the sliding seat 41, and the pressure post 411 abuts against the side wall of the pull rod 42.

[0041] In some embodiments, as Figure 4 and Figure 5 shown, for the convenience of connection and driving, the pull rod 42 is hinged to the movable clamping member 32 through a connecting rod 43. One end of the connecting rod 43 is hinged to the pull rod 42, and the other end is hinged to the movable clamping member 32. Among them, a first hinge seat 422 is symmetrically provided at one end of the pull rod 42, and a second hinge seat 321 is symmetrically provided at one end of the movable clamping member 32. One end of the connecting rod 43 is hinged between the two first hinge seats 422, and the other end is hinged between the two second hinge seats 321.

[0042] In some embodiments, as Figure 4 and Figure 5As shown, movable clamping members 32 are slidably installed on both sides of the main clamping member 31. By using two movable clamping members 32, the effect of clamping the cloth is better. A spring 33 is installed between the two movable clamping members 32, and the spring 33 always makes the movable clamping members 32 tend to move away from the main clamping member 31. Among them, one end of the movable clamping member 32 is provided with an extension portion 322 towards the inner side, and a limit groove 323 is provided on the extension portion 322, and the spring 33 is placed in the limit groove 323.

[0043] In a preferred embodiment, as Figure 5 and Figure 6 shown, a limit projection 421 is provided on the side wall of the pull rod 42, and the limit projection 421 can limit the upward sliding of the pressing column 411, so that the cloth clamping assembly 3 maintains a clamped state. Since the spring 33 is installed, it is necessary to set the limit projection 421 to limit the pressing column 411 to prevent the movable clamping member 32 from resetting after the external force for pressing down the inner rod 22 disappears, thereby ensuring that the cloth clamping assembly 3 maintains a clamped state. When it is necessary to replace the mop cloth, pull up the inner rod 22. After the upward force of the pressing column 411 exceeds the limiting force of the limit projection 421, under the action of the spring 33, the movable clamping member 32 resets and the cloth clamping assembly 3 loosens.

[0044] In some embodiments, as Figure 4 and Figure 5 shown, there are two movable clamping members 32. Convex seats 412 are symmetrically arranged on both sides of the sliding seat 41, and pressing columns 411 are symmetrically arranged on the convex seats 412. A pull rod 42 is symmetrically installed between the two pressing columns 411. One corresponding end of the two pull rods 42 is hinged to the mop head 1, and the other end is connected to the corresponding movable clamping member 32. That is, the number of sliding seats 41 is one, the number of pressing columns 411 is four, and the corresponding numbers of pull rods 42 and connecting rods 43 are both four; this structure is beneficial to ensuring the stability of the structure and reliable driving.

[0045] In some embodiments, as Figure 3 and Figure 8 shown, the sliding seat 41 is connected to the inner rod 22 through an inner connecting seat 23. One end of the inner connecting seat 23 is hinged to the sliding seat 41, and the other end is hinged to the inner rod 22. The outer rod 21 is connected to the mop head 1 through an outer connecting seat 24. One end of the outer connecting seat 24 is hinged to the outer rod 21, and the other end is hinged to the mop head 1. The inner connecting seat 23 is located inside the outer connecting seat 24.

[0046] In some embodiments, as Figure 2 、 Figure 3 and Figure 7 shown, a first tooth portion 311 is provided at the side end of the main clamping member 31, and a second tooth portion 324 that can be engaged with the first tooth portion 311 is provided on the movable clamping member 32. The mop cloth is clamped through the cooperation of the first tooth portion 311 and the second tooth portion 324, and the clamping effect is better.

[0047] In some embodiments, such as Figure 9 shown, a connecting portion 325 is provided on the inner side of the movable clamping member 32, and limiting chucks 101 are provided on one or both sides of the inner wall of the mop head 1 where the connecting portion 325 and the extending portion 322 are located. In this way, the connecting portion 325 and the extending portion 322 are limited and guided by the limiting chucks 101, and the movable clamping member 32 has good sliding stability on the mop head 1.

[0048] The using process of the cloth clamping mechanism of this cloth clamping mop is as follows:

[0049] When clamping the cloth, lay the mop cloth flat on the ground, and then place the mop head 1 on the mop cloth; then press down the inner rod 22, the inner rod 22 drives the sliding seat 41 to slide down, the sliding seat 41 drives the pressing column 411 to slide down, the pressing column 411 pushes the pull rod 42 to swing inward, and the pull rod 42 drives the movable clamping member 32 to approach the main clamping member 31 through the connecting rod 43, so as to clamp the mop cloth.

[0050] For the same and similar parts among the various embodiments in this specification, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0051] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
